Implementation

Future<T?> uploadMultiple<T>(
  String url, {
  required Map<String, String> files,
  Map<String, dynamic>? additionalFields,
  ProgressCallback? onProgress,
  CancelToken? cancelToken,
}) async {
  final Map<String, dynamic> formMap = {...?additionalFields};

  for (final entry in files.entries) {
    formMap[entry.key] = await MultipartFile.fromFile(entry.value);
  }

  final formData = FormData.fromMap(formMap);

  return await network<T>(
    request: (request) => request.postUri(
      Uri.parse(url),
      data: formData,
      cancelToken: cancelToken,
      onSendProgress: onProgress,
    ),
  );
